A kind of enterococcus faecium and preparation method thereof

Abstract

The invention discloses enterococcus faecium and a preparation method thereof, relates to the field of microorganisms, and particularly relates to the enterococcus faecium and application thereof. A bacterium sample is acquired from the rumen of a slaughtered goat, subjected to directive breeding at the temperature of 32-42 DEG C under an anaerobic and photophobic condition, and separated and purified by use of a repeated divisional agar streak plate method so as to obtain enterococcus faecium L-01. The enterococcus faecium L-01 can be used as an animal microorganism fodder additive, has the effects of effectively inhibiting pathogenic bacterium in animal digestive tract, improving the micro-ecological environment of the digestive tract and enhancing the immunologic function of an animal body, can be used as a substitute product of antibiotics and can be used for effectively solving the existing serious situation.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to an enterococcus faecium and its application. Background technique [0002] At present, due to a series of problems such as the abuse of antibiotics and the emergence of super bacteria, human beings are inevitably faced with the serious situation caused by this. It is imperative to develop antibiotic substitutes as soon as possible to provide green, safe and efficient animal feed and human food. Production provides reliable technical support. Prebiotics are a new type of feed additive developed in the past 20 years, which have the functions of antibiotics and enzymes. Probiotics can replenish beneficial flora, improve the balance of digestive tract flora, prevent and treat flora disorders; stimulate the body's immune system and improve the immune ability of animals; participate in the survival competition of flora, and assist the body to eliminate toxins and metabolites; It can imp...
